Ozone+Hole+and+Global+Warming

What is an Ozone? An Ozone is a gas that lies in the highest part of the earth's atmosphere and also near ground level. The Ozone can have a positive or negative affect on the health and environment of many depending on its location.

The Ground level Ozone, also called the Troposphere is consisted of the air near the earth's surface. This air is considered the "pollutant" and can cause health risks, damage to crops and various vegetation and is titled the "Urban Smog".

The Stratospheric Ozone (uppermost part of atmosphere) is considered 'good' and acts as a protector from the sun's UV rays.

What most believe is the cause to Global Warming? -Ozone depletion (the growth of the hole in the Ozone layer) allows more of the Sun's UV rays to hit the earth and begin to melt the ice caps.

What is really going on: The natural shield is beginning to lose its stability due to the man-made chemicals being produced by ourselves such as Chlorofluorocarbons (CFC's). This allows more UV rays to hit the ground and can lead to negative affects such as skin cancer, cataracts and other problems affecting health and the environment.

Global warming is caused by carbon dioxide, methane, nitrous oxide and other chemicals which create greenhouse gases. This is caused by the trapping of these chemicals in the lower most part of the atmosphere and with this, increases the earths temperature because the sun rays are unable to escape.

Scientists are to believe that this is occurring! GLOBAL WARMING IS REAL. [Second Assessment of the Intergovernmental Panel on Climate Change (IPCC)].

Humans are the cause to Global Warming. We often produce greenhouse gases (stated above) which cause negative affects such as a rise in the sea level, storms, droughts, heat waves, deforestation, etc.



Scientists gave fund that the 10 hottest years have been recorded in the past 15 years. By examining growth rings in certain trees and drilling in the ice cores located in Antarctica, scientists have determined that this past decade was recorded the warmest in more than 4 centuries.

The more severe Global Warming is, the faster the process of Ozone Depletion. During research, scientists are beginning to worry that this continuation will increase the rate at which the ozone is being destructed.

More negative affects occur when the stratosphere becomes colder due to global warming trapping heat in the troposphere, preventing heat from entering the stratosphere. Greenhouse gases trap the temperature of the atmosphere in and this begins to increase the depletion of the Ozone layer.
